“…The development of intrinsically stretchable electronics has been challenging due to the need to create new materials with suitable mechanical and electronic properties 41,42 . Examples of such materials include composites in which electronic functionality is imparted to insulating elastomers by blending them with electronically active components 40,43 .…”

Skin plays an important role in mediating our interactions with the world. Recreating the properties of skin using electronic devices could have profound implications for prosthetics and medicine. The pursuit of artificial skin has inspired innovations in materials to imitate skin's unique characteristics, including mechanical durability and stretchability, biodegradability, and the ability to measure a diversity of complex sensations over large areas. New materials and fabrication strategies are being developed to make mechanically compliant and multifunctional skin-like electronics, and improve brain/machine interfaces that enable transmission of the skin's signals into the body. This Review will cover materials and devices designed for mimicking the skin's ability to sense and generate biomimetic signals.

“…Downscaling optoelectronic sensing and actuating units to micro‐ or even nanometer dimensions is of relevance for miniaturizing photonic integrated circuits and lab‐on‐a‐chip concepts. Especially organic semiconductor‐based electronics emerge as a communication bridge to biological tissue . They are favorable due to their easily tunable properties and capability to readily self‐assemble into a micro‐ or nano‐textured morphology with inherently connected local anisotropic optoelectronic response .…”

Local polarized surface photovoltage (SPV) spectroscopy is used to characterize an organic squaraine‐fullerene photovoltaic layer blend. The anisotropic optical response of the textured photoactive layer is dominated by the largely Davydov‐split absorption within the deep red of the crystallized donor compound. Through knowledge of the crystallographic texture, the local molecular in‐plane orientation is deduced. Kelvin probe force microscopy (KPFM) maps the differential SPV of the active layer on the nanoscale without complications by interfaces, which is spatially correlated with the pleochroic optical response of the thin film. The SPV shows a wavelength‐dependent, bichromatic change upon rotating the polarization axis of the illuminating light. With that subtler, nanoscaled optoelectronic sensing or actuating platforms become possible.

“…[1][2][3][4][5][6] Materials decorated with self-healing feature could boost the lifetime of products and build new potentials in various areas. 7 Selfhealing conductors are currently attracting a significant number of studies, [8][9][10][11][12][13][14][15][16] particularly for advanced electronic applications, including chemical sensors, 17 thermal sensors, 18 supercapacitors, [19][20][21] lithium-ion batteries, 2 and electronic skin. 7,22 Similarly, flexible conductors play an important role in the emerging fields, such as prosthetics, soft robotics, stretchable displays and human machine interfaces.…”

Intrinsic self-healing polyborosiloxane (PBS) and its multi-walled carbon nanotube (MWCNT)-reinforced nanocomposites were synthesized from hydroxyl terminated poly(dimethylsiloxane) (PDMS) and boric acid at room temperature. The formation of Si-O-B moiety in PBS was confirmed by Fourier transform infrared spectroscopy. PBS and its MWCNT-reinforced nanocomposites were found possessing water or methanol activated mechanically adaptive behaviors; the compressive modulus decreased substantially when exposed to water or methanol vapor and recovered their high value after the stimulus was removed. The compressive modulus was reduced by 76%, 86%, 90% and 83% for neat PBS and its nanocomposites containing 3.0 wt.%, 6.2 wt.% and 13.3 wt.% MWCNTs, respectively, in water vapor, and the modulus reduction activated by methanol vapor was greater than by water vapor. MWCNTs at higher contents acted as a continuous electrical channel in PBS offering electrical conductivity, which was up to 1.21 S/cm for the nanocomposite containing 13.3 wt.% MWCNTs. The MWCNT-reinforced PBS nanocomposites also showed excellent mechanically and electrically self-healing properties, moldability and adhesion to PDMS elastomer substrate. These properties enabled a straightforward fabrication of self-repairing MWCNT/PBS electronic circuits on PDMS elastomer substrates.

Abstract: The carbon framework common to both organic semiconductors and biological structures suggests that these two classes of materials should be easily integrated.
